Fuel consumption and emission improvements obtained using a mild hybrid electrical system on a vehicle equipped with a manual gearbox

Abstract

The latest emission requirements for vehicles requires major improvement in vehicles fuel consumption and emission performance. For entry level range of vehicles, in order to keep the production costs low, the simplest choice of hybridization is the mild-hybrid system with integrated starter-generator (ISG). This paper contains a model of a mild-hybrid electric vehicle equipped with a manual gearbox and a model of conventional vehicle with focus on the emission performance. The goal of this paper is to find out the fuel consumption and emission of a mild hybrid electric vehicle by simulation and to show the improvements compared to a similar vehicle equipped with a conventional powertrain.
